Professional Applications & Engineering Value

This heavy-duty Schedule 80 stainless steel pipe nipple delivers critical engineering solutions for industrial fluid systems where reliability is paramount. The seamless 304/304L stainless steel construction eliminates potential failure points common in welded alternatives, providing superior resistance to corrosion, pressure cycling, and thermal stress. With NPT threading on both ends, it ensures leak-tight connections in high-pressure applications involving hydraulic systems, steam lines, and gas distribution. The thick-wall design maintains system integrity under extreme operating conditions while the corrosion-resistant properties prevent contamination in sensitive processes. Engineered for 3000 class fittings and 300/600 class flanges, this nipple serves as a durable connection point in chemical processing, power generation, and industrial manufacturing where system failures can result in costly downtime.

Specification Summary & Compliance

This product features precision NPT threading conforming to ASME B1.20.1 standards with dimensions of 1 1/4" pipe size, 12" length, 1.278" ID, and 1 21/32" OD with 0.191" wall thickness. Manufactured according to ASTM A733 specifications for seamless stainless steel pipe, it ensures consistent performance across industrial applications. The nipple is RoHS 3 (2015/863/EU) compliant and designed for compatibility with 304/304L stainless steel fittings and flanges rated for Class 3000 and 300/600 service conditions respectively.
